WebSo in the dot product you multiply two vectors and you end up with a scalar value. Let me show you a couple of examples just in case this was a little bit too abstract. So let's say that we take the dot product of the vector 2, 5 and we're going to dot that with the vector 7, 1. Well, this is just going to be equal to 2 times 7 plus 5 times 1 ... WebAssume Ist, Ist1 and Ist2 are lists of the appropriate type that supports addition, multiplication and modulo operator on the elements. Note: dot product of two lists of same size is defined as [e1, ..., en] - [f1, ..., fn] = (e1* f1 + 2 * f2 + ... + en * fn) Select all odd elements from list. Sum of square of each element in the list.
